BOILER-FLUE CONNECTION.

Specicaticn of Letters Patent. Patented Fel). 11, 1919.

Application led September 12, 1918. Serial No. 253,695.

To all whom t may concern:

Be it known that I, FRANK NEwsHUTZ, a citizen of the United States, residing at Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Boiler-Flue Connections, of which the following is a speciHca tion.

rIhis invention relates to new and useful improvements in boiler Hue connections for locomotives or other steam engines.

The primary objects of this invention are, first, to provide a boiler Hue connection which is simple and economical in construction, second, that will last for a considerably longer time than the kind now in use and third, will provide an absolutely water and steam tight joint between the ends of the Hue and the Hue sheet or wall and prevent any water or steam from blowing into the Hues.

With the foregoing and other objects in view that will appear as the nature of the invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts illustrated in the drawings and more particularly pointed out in the appended claims.

In the accompanying drawings Figure l is a fragmentary sectional view of one end of a boiler Hue and the Hue wall or sheet, illustrating the application of my invention.

Fig. 2 is a front view of Fig. 1 and Fig. 3 a detail edge view of a brass or copper packing element used or interposed between the clamping plug and the end of the Hue, at the joint.

Referring to the drawings for a more particular description of the invention and which drawings are for illustrative purposes only and are therefore not drawn to scale, the numeral 1 indicates the Hue wall or sheet and 2 the adjacent end ofthe Hue. As shown, said end of the Hue, at the joint, is considerably thickened, as at 3, and is slightly offset inwardly, leaving an annular space between the outer surface of said thickened portion and the wall or edge of the Hue opening 4 in which is arranged a packing ring 5 of brass, copper or other suitable material. The Hue opening 4 is provided in its outer portion with an annular or circumferential recess 6, and in carrying out the invention, the outer end of the thickened portion 3 of the Hue is bent or crimped inwardly, as at 7, over the packing ring 5 against the vertical wall 8 of said recess 6.

A clamping ring 9, comprising a body portion 10 and an annular exteriorly threaded head or rim 1l, is screwed into the recess 6 of the Hue opening, the body portion of said clamping ring Htting within the thickened end portion of the Hue and the inner face of the head or r'im of said ring provided with an annular concave recess 12.

It will be observed that an annular or circumferential space 13 is left between the outer surface of the-body portion of the clamping ring and the inner edge or wall of the thickened end portion of the Hue to receive a packing ring or gasket 14 of brass, copper or other suitable material, the outer portion of which ring or gasket 14e is adapted to Ht in the concave recess 12 in the head or rim of the clamping ring and is bent or crimped inwardly, as at 15, against the inturned Hange 7 of the thickened end p0rtion 8 of the Hue.

It will be noted that the threaded clamping ring keeps the eXtreme heat 0H' the wall of the Hue at the joint; also, that the head or rim of the clamping ring keeps the water and steam from leaking into the Hue and coming in contact with the fire, thus allowing the engine to steam more freely. The copper gasket forms an absolutely water and steam tight joint and prevents the water and steam from blowing into the Hue, even should the Hue leak.

From the foregoing description taken in connection with the drawings, it is thought that the construction, operation and advantages of this invention will be readily understood without requiring a more extended eX- planation.

I-Iaving described my invention, what I claim as new and desire to secure by Letters Patent, is

l. In combination with a boiler Hue wall. or sheet formed with a counter bore or annular recess in the Hue opening, a Hue formed at one end with a thickened portion extending into the Hue opening and bent or crimped inwardly against the vertical wall of said counter bore, a metallic gasket encompassing the thickened inwardly bent portion of the Hue and a clamping ring screwing into the counter bore of the Hue opening against said gasket.

2. In combination with a boiler flue wall or sheet formed with a counter bore or annular recess inthe lue opening, alue formed at one end with a thickened portion eXtending into the flue opening and bent or crimped inwardly against the vertical wall of said counter bore, a metallic gasket encompassing the thickened inwardly bent portion of the iue, a clamping ring screwing into the counter bore of the "iue opening against said gasket and a clamping ring between the thickened end portion of the `flue and the inner edge of the flue opening.

In'conibination with a boiler Hue wall or sheet 1formed with' a counter bore in the iue openingpa iiue Jformed at one end with a thickened 'portion extending into the flue opening jand bent or crimped inwardly against the vertical wall of said counter bore, 'said thickened portion being slightly offset inwardly, a metallic gasket encompassing the Vthickened inwardly bent portion 'Copies o1" 'this patent may be obtained for of the iiue, a clamping ring screwing into the counter bore of the flue opening against said Vgasket and a clamping ring between the thickened o set end portion of the iue and the inner edge of the flue orpenin` 4f. In combination with a boiler fine wall or sheet formed with a counter bore in the iiue opening-,a "iue Vformed at one end with a thickened portion extendingvinto the flue opening and bent or crimped .inwardly against the YVertical Wall ofsaid vcounter bore, a metallic gasketl y encompassing the thickened end portion 4of said flue and a clamping ring screwii'ig into the 'counter bore of the flue opening and formed in the inner edge of its head or rim with an annular circumferential recess to receiveV the inwardly bent or crimped portion "of said gasket. Y n d l A In testimony vwhereof I aliiir 'my signature.
